It could be worth mentioning that a possible 4th decent option is to turn right at the NE Shoulder down to the Tacul and descend the normal route. In fact, if you reach the NE shoulder anytime after 14:00 I would use this option. When I did this route I choose to continue to the summit and I ended up being Airlifted out by Helicopter from the Col. Me and my partner basically ran out of energy and the weather turned quite bad
